Ah, I thought that this is what you are trying to achieve, I did not question the meaningfulness of using a Pi for this purpose. Just saying, if you are targeting just a few units of your device then one of the < 10$ Linux computers (CHIP, Orange Pi Zero, ...) with WiFi and Bluetooth might be even more economic than an Arduino - especially when it comes to development time. Personally, I'm all in favor of using Android to create a nice looking pendant app. I have also created a pendant smartphone app with jog wheel and physical vibration feedback: https://www.roessler.systems/wp-content/uploads/2017/11/screener_1514997231493.png you can read more on my website: https://www.roessler.systems/ Unfortunately that's not open source, but you get the idea. -- Alexander -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
